twister method consists in drawing the yarn through water prior towinding same on the cones 9. These'methods are objectionable, however,due to the expense of handling and storage of the yarn in the one caseand the absorption of too much moisture by the yarn in the other.

According to my invention a trough 10 is supported from a beam 11 bymeans of brackets 12 which project outwardly and upwardly between theaprons 6, the trough being suitably secured to the ends of thesebrackets in position to overlie the aprons. Mounted to rotate in thistrough is a shaft 13 provided with spaced enlargements or 70 sleeves letfixed thereto throughout its length, there being an enlargement for eachspindle 8 and'in the path of travel of the thread 7 from the spindles tothe cones 9. These enlargements are half submerged in the water 15 intrough 6. The shaft 13 is constantly rotated at a very slowpredetermined rate of speed by any suitable means (not shown). The yarn7 travels at a very high rate of speed as itis unwound from the spindles8 and consequently very little moisture is taken up by the yarn as itcontacts with the enlargements. By regulating the speed of rotatlon ofthe shaft 13 to the proper ratio of speed of travel between saidshaftand the yarn the amount of moisture which the yarn will take up canbe regulated to a nicety. In practice it has been found that cotton yarngives best results when containing about 7% moisture.

By providing the shaft 13 with the enlargements 14 a substantial surfaceis at all times out of contact with the water in the trough 6 andconsequently comparatively little moisture is carried by the exposedhalf of these enlargements. It thus follows that" the yarn cannot becomesaturated with water as in the so called wet twister method.

In Figure 4 I have illustrated a modification of my invention wherein Isubstitute 100 for the rotary shaft 13 a stationary pipe 16 containingwater 17. This pipe is formed with a number of branch pipes 18containing wicks 195- These wicks are adapted to be positioned in thepathof and be engaged 10 by the yarn 7 in its passage between thespindles 8 and the cones 9.

Lin Figure 5 a still further modification of my invention is illustratedwherein a stashaft 13. Loosely mounted for rotation on the shaft 29 area plurality of rollers 20 which take the place of and function in likemanner to the sleeves or enlargements 14. The frictional eng ement ofthe yarn with the rollers causes t e latter to slowly rotate in thewater, it being understood that a trough 6 is employed and also that therollers 20 are half submerged in the Water 15 in the trough.

Having thus described my invention what I claim is:
